It is the second incident this summer for the company, which recalled 22,000 pounds of beef in June over concerns of E. coli contamination.

The meat in the latest recall was produced on July 18, and ” shipped in 40 to 60 pound cases to retailers, wholesalers and food service distributors nationwide,” the USDA said in a news release.

It’s unclear whether it was sold at a retail level.

The product carries the USDA mark of inspection, bearing the establishment number “EST. 208A”. The possibility of contamination was raised in a routine Food Safety and Inspection Service inspection.

E. coli O157:H7 is a potentially deadly bacteria found in recent years in various food products, including raw beef and prepackaged greens, such as spinach and salad mixes. The USDA warns that it causes “bloody diarrhea, dehydration and in the most severe cases, kidney failure.”

Approximately 76,000 people are infected with E. coli every year, according to the Centers for Disease Control and Prevention.

CNN has reached out to the National Beef Packing Co. for comment, but has not yet received a response.
